[0002] Table salt, also known as edible salt, is a condiment whose main ingredient is sodium chloride. It plays an important role in people's daily diet, not only increasing the taste of food and making it more delicious, but also has important physiological functions.

[0003] The production of salt has a long history, and China's salt production can be traced back to ancient times. Ancient people obtained salt by drying seawater, mining rock salt, and extracting well water. With the development of science and technology, modern industrial salt production methods such as vacuum evaporation, electrolysis, ice crystal separation, and ion exchange have also been widely used.

However, the existing salt crystallization and filtering equipment is not convenient for cleaning the impurities generated by the filtration when filtering the crude salt solution. At the same time, it is not convenient to remove the solution retained on the impurities during the cleaning process, which easily causes unnecessary waste.

[0005] Therefore, it is very necessary to invent a kind of salt crystallization filtering equipment. Utility Model Content

Through the setting of the plugging mechanism 9, during the process of filtering the crude salt solution by the first filter cartridge 3 and the second filter cartridge 4, leakage of the dissolved liquid can be prevented;

[0027] The slag removal mechanism includes a bracket 6, an electric push rod 1 7 and an electric push rod 2 8, and the electric push rod 1 7 and the electric push rod 2 8 are fixedly installed on both sides above the bracket 6. Through the setting of the bracket 6, the stability of the electric push rod 1 7 and the electric push rod 2 8 can be guaranteed, and the output ends of the electric push rod 1 7 and the electric push rod 2 8 are fixedly installed with piston heads 10 respectively; the piston head 10 on the electric push rod 1 7 slides into the first filter cartridge 3 through the slag discharge port 12, and the impurities in the first filter cartridge 3 can be pushed out from the slag discharge port 12 by the setting of the electric push rod 1 7 and the piston head 10; the piston head 10 on the electric push rod 2 8 slides into the second filter cartridge 4 through the slag discharge port 12, and the impurities in the second filter cartridge 4 can be pushed out from the slag discharge port 12 by the setting of the electric push rod 2 8 and the piston head 10.
